For monthly Pulse subscriptions: all major US credit and debit cards.
For annual Pulse subscriptions (12 months prepaid at a discount): cards OR ACH from your business bank account.
During the 90-day free trial there is no card on file. We email you 30 days, 7 days, and 1 day before it ends with a link to subscribe — if you do nothing, Pulse simply pauses and you are never billed.
